WARNING

There c ould be a Database Mismatch. Changes made with the 375 may not be recorded in the Host System database. Ensure all safety precautions and work procedures have been followed.

If this segment is connected to a Host System, the changes made with the 375 may not be recorded in the Host System’s permanent data base. Verify the changes in the database. Otherwise, this could cause unpredictable results and, depending upon your application, process disruption leading to property damage, serious injury, or death.

Process control could be affected. Changing device parameters could adversely affect the control of your process.

Ensure all safety precautions and work procedures have been followed. Put control loop in Manual/Out of service before applying changes. Verify output before returning control loop to Auto. Failure to do so could result in property damage, death or serious injury.

BASIC FEATURES AND FUNCTIONS

Fieldbus Functionality

Link Active Scheduler (LAS)

All segments have one and only one Link Active Scheduler (LAS). The LAS operates as the bus arbiter for the segment. The 375 Field Communicator is set up to always be the last node to become the LAS on a segment.

The devices that are capable of becoming the LAS are called link master devices. All other devices are referred to as basic devices. When a segment first starts up, or upon failure of the existing LAS, the link master devices on the segment bid to become the LAS. The link master that wins the bid (i.e. the one with the lowest address) begins operating as the LAS immedi atel y upo n completion of the bidding process. Link masters that do not become the LAS can act as LAS backups by monitoring the segment for failure of the LAS and then bidding to become the LAS when a LAS failure is detected.

Only one device can communicate at a time. Permission to communicate on the bus is controlled by a centralized token passed between devices by the LAS. Only the device with the token can communicate. The LAS maintains a list of all devices that need access to the bus. This list is called the “Live List”; see

“Displaying the Live

Device List” on page 4-11.

Page 61

Fieldbus Functionality

4-3

Interoperability

375 operation with other hosts

The 375 Field Communicator is designed to operate with a wide range of F

OUNDATION fieldbus

devices independent of device manufacturer. Interoperability is achieved through the use of Device Description Language (DDL) technology supported by the Fieldbus Foundation.

Basic testing is performed on all DDs. In addition, each device manufacturer is asked to certify that they have thoroughly tested their device(s) with the 375 Field Communicator. If certification is not received, a warning message will display when you attempt to access an untested device.

When a 375 Field Communicator is connected to a live fieldbus segment and a host system, it joins the fieldbus segment but not as the LAS. This means that, although the 375 Field Communicator can view and edit device parameters, the control of the segment is still handled by the node that is designated the LAS for the segment. You can also read and write if there is another LAS. Prior to connecting to a host system review the 375 Field Communicator Host Testing Summary on www.fieldcommunicator.com.

ST_REV ST_REV is a block parameter that increments

each time a block configuration has changed. While a list of parameters is displayed, the 375 Field communicator will continuously read the ST_REV of that particular block. If it sees the ST_REV counter has incremented, it knows that there has been a change to the block, and it will automatically refresh (reread) all of the block

parameters. Thus, there would only be a very short period of time before a change made by another host would appear on the 375 display.

Page 62

4-4

Fieldbus Functionality

Modes The Resource, Transducer, and all function blocks

in the device have modes of operation. These modes govern the operation of the block. Every block supports both automatic (AUTO) and out of service (OOS) modes. Other modes may also be supported.

Types of Modes

For the procedures described in this manual, it will be helpful to understand the following modes:

AUTO

The functions performed by the block will execute. If the block has any outputs, these will continue to update. This is typically the normal operating mode.

Out of Service (OOS)

The functions performed by the block will not execute. If the block has any outputs, these will typically not update and the status of any values passed to downstream blocks will be “BAD”. Before you make changes to the configuration of the block, change the mode of the block to OOS. When the changes are complete, change the mode back to AUTO.

MAN

In this mode, the output of the block can be manually overwritten for testing purposes.

Other Types of Modes

Other ty pes of modes are Ca s, RCas , ROut, IMan and LO. For more information; see the Emerson Process Management, Rosemount Division Func tion Block ma nual, document 00809-0100-4783.

Page 63

Locating Mode Parameters

In the Resource and Transducer blocks, the mode parameters are normally found in the Process menu. In all other Function blocks, they are found in the Common Config. menu. The Mode parameters will also be included in the All parameter list; see

“Working with Device Blocks”

on page 4-13.

Changing Modes

A warning message may appear whenever the mode of any block is included in a list of parameter changes to be sent to a device. Press YES to send the change, or NO to not send the change.

To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a short delay, the parameter MODE_BLOCK.ACTUAL should reflect the mode change if the block is operating properly.

Permitted Modes

It is possible to prevent unauthorized changes to the operating mode of a block. To do this, configure MODE_BLOCK.PERMITTED to allow only the desired operating modes. It is recommended to always select OOS as one of the permitted mode s.

375 FIELD COMMUNICATOR

SECTION 5TROUBLESHOOTING

OVERVIEW This section provides basic troubleshooting

techniques for the Model 375 Field Communicator. Below are methods for troubleshooting HART

Networks that are experiencing problems communicating between a field device and the 375 Field Communicator.

Troubleshooting suggestions

Answer the questions below and use the troubleshooting table,

Table 5-4,before calling

technical suppor t per sonnel.

• Does the control system have HART communication capabilities?

• Is it configured to communicate HART currently? If so, is it reporting communication problems? If not, stop HART communications on the control system and test communication with the 375 Field Communicator again.

• Is there a barrier installed?

• Is the barrier capable of passing along the HART signal?

www.fieldcommunicator.com

Page 80

5-2

Troubleshooting

Loops

Verify the HART loop current and voltage on the field device. Almost all field devices need at least 4mA and 12VDC to operate properly.

If there are multiple field devices on a multidrop loop then set the 375 Field Communicator to digital polling mode.

Inspection of the loop wiring can often times reveal problems. The shield is normally grounded at one end only, which is usually the control system.

Verify that the loop has a minimum of 250 ohms resistance. If there is not an external resistor, then normally, the total resistance is the resistance of the process-indicating device monitoring the loop. Check the manuals for the process-indicating device to determine it's loop resistance. If the resistance of the process-indicating device is unknown it can be determined by knowing the current flow in the loop and the voltage across the process-indicating device.

The resistance can be calculated using the formula, Resistance = Voltage / Current. The 375 Field Communicator can be used to measure the voltage; see

“DC voltage measurement (HART

terminals) ” on page 3-22.

Page 81

Troubleshooting

5-3

Sample values

Loop Current Flow Minimum voltage for 250 ohms. 4 ma 1 Volt

8 ma 2 Volts 12 ma 3 Volts 16 ma 4 Volts 20 ma 5 Volts

If the voltage across the process-indicating device is greater than the value listed for a given current flow then the device has at least 250 of internal resistance. If the voltage is less than the value listed on the table for the given current flow, then more resistance needs to be added to the loop.

If an oscilloscope is available for use then use it to look for noise on the loop. It is necessary to use a a scope with differential mode capability or a battery powered/isolated scope to avoid grounding one side of the loop. Noise with a frequency of 500 Hz to 10,000 Hz is of particular interest, as this represents frequencies near the HART frequencies of 1200 and 2200 Hz.
